通过在Volley Library中使用Intent，无法从片段移动下一个Activity

Question

I am trying to login by using volley library. I have used SharedPrefrences to store User name,email,mobile. When I am using correct mobile no. and password. Toast is generating to login successful but not able to move Login Fragment to Dashboard Activity.

Here is the Code of login method

private void login(String login_url, final String getLoginMob, final String getLoginPwd) {

    //Progress Dialog code
    final Dialog dialog =new Dialog(getActivity());
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialog.setContentView(R.layout.loading_dialog);
    dialog.setCancelable(false);
    dialog.show();

    RequestQueue queue = Volley.newRequestQueue(getActivity());
    StringRequest postrequest = new StringRequest(Request.Method.POST, login_url, new Response.Listener<String>() {


        @Override
        public void onResponse(String response) {
            dialog.dismiss();

            try {
                JSONObject jsonObject = new JSONObject(response);

                if (jsonObject.getBoolean("success") == true ) {
                    Toast.makeText(getActivity(),jsonObject.getString("message"),Toast.LENGTH_LONG).show();

                    JSONObject jsonObjectInfo=jsonObject.getJSONObject("User");
                    sharedPrefrence_main.setName(jsonObjectInfo.getString("name"));
                    sharedPrefrence_main.setEmail(jsonObjectInfo.getString("email"));
                    sharedPrefrence_main.setMobile_no(jsonObjectInfo.getString("mobile"));

                    Intent intent=new Intent(getActivity(), Dashboard.class);
                    startActivity(intent);


                } else if (jsonObject.getBoolean("success") == false) {
                    Toast.makeText(getActivity(), jsonObject.getString("message"), Toast.LENGTH_LONG).show();
                }
                else
                    Toast.makeText(getActivity(),"Entries are wrong",Toast.LENGTH_LONG).show();


            } catch (JSONException e) {
                e.printStackTrace();
            }
        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            error.printStackTrace();
            dialog.dismiss();
        }
    }){
        @Override
        protected Map<String, String> getParams(){
            Map<String,String> param=new HashMap<String, String>();
            param.put("mobile_email", getLoginMob);
            param.put("password", getLoginPwd);
            return param;

        }
    };

    int socketTimeout = 30000;
    RetryPolicy policy = new DefaultRetryPolicy(socketTimeout,
            DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
            DefaultRetryPolicy.DEFAULT_BACKOFF_MULT);
    postrequest.setRetryPolicy(policy);
    queue.add(postrequest);

}

JSON Response

{"success":"true","message":"Login Sucessfully","User":[{"name":"satishkanaujiya ","email":"*****@gmail.com","mobile":"901589****"}]}

Answer 1

  runOnUiThread(new Runnable() {
        @Override
        public void run() {
            //Type your Intent code here
        }
    });

Answer 2

This is an array and I was treating it as objects. Finally I corrected my mistakes by following codes.

                JSONArray jsonArrays=jsonObject.getJSONArray("User");
                for(int i=0;i<jsonArrays.length();i++){
                 JSONObject jsonObject1=jsonArrays.getJSONObject(i);
                    sharedPrefrence_main.setName(jsonObject1.getString("name"));
                    sharedPrefrence_main.setEmail(jsonObject1.getString("email"));
                    sharedPrefrence_main.setMobile_no(jsonObject1.getString("mobile"));

                }
